Cr4+:YAG Crystal is an excellent crystal for passively Q-switching diode pumped or lamp-pumped Nd:YAG, Nd:YLF, Nd:YVO4 or other Nd and Yb doped lasers at wavelength from 0.8 to 1.2 µm. Passive Q-switches or saturable absorbers provide high power laser pulses without electro-optic Q-switches, thereby reducing the package size and eliminating a high voltage power supply. Cr4+:YAG is more robust than dyes or color centers and is the material of choice for 1 µm Nd lasers. Passive Q-switched lasers incorporating Cr:YAG crystals have been extensively manufactured at low cost and with reduced system size and weight.
